hohmann2002_freqz - Frequency response of hohmann2002 filter or filterbank
Usage
h = hohmann2002_freqz(filter, z) H = hohmann2002_freqz(fb, z)
h = hohmann2002_freqz(filter, z) returns the frequency response of filter created by hohmann2002_filter.
h = hohmann2002_freqz(fb, z) returns the frequency responses of the individual filters in the filterbank fb created by hohmann2002. The responses of the individual filters are stored in columns of h.
Input parameters
| '',filter | A filter created by hohmann2002_filter. |
| '',fb | A filterbank created by hohmann2002. |
| '',z | A vector of frequencies in z-plane for which the frequency response will be computed. \(z = \exp(2i\cdot pi\cdot f/fs)\) |
Output parameters
| '',h | The complex frequency response at z. Each column represents a response of a filter. |
